采用环形器和部分反射光纤布拉格光栅作为腔端，在线性腔光纤激光器结构中实现了单纵模选择。在1551 nm波长下，采用多个子环腔作为模式滤波器，测得信噪比为56 dB，线宽小于1 MHz。通过将剩余泵浦功率回收到增益介质中，泵浦效率提高了10%。
A single-longitudinal-mode selection is realized in a linear-cavity fiber laser construction using a loop-back optical circulator and a partial reflectance fiber Bragg grating as the cavity ends. At 1551 nm wavelength, the measured signal-to-noise-ratio is 56 dB and with a line width less than 1 MHz obtained using multiple subring cavities as mode filters. The pumping efficiency is 10% improved by recycling the residual pump power to gain medium.
